Product information "NOA 63 Optical Adhesive 1oz bottle"
Viscosity at 25°C: 2000 cps, Refractive Index: 1.56
Norland Optical Adhesive 63 ("NOA63") is a clear, colorless, liquid photopolymer that will cure when exposed to ultraviolet light. Since it is a one part system and 100% solids,it offers many advantages in bonding of optical elements where the bonding surface can be exposed to light. The use of NOA 63 eliminates premixing, drying or heat curingoperations common to other optical adhesive systems. Curing time is remarkably fast, and is dependent upon the thickness applied and the amount of ultraviolet light energy available.
NOA 63 is recommended for the bonding of achromats, prisms and all other precision compound optics. The outstanding characteristics of the adhesive are its low fluorescence and its excellent transmission in the near UV range. After fullcure, the adhesive has good transmission from 320 to 3,000 nanometers.
